ADCMP572BCPZ-R2

Overview

The ADCMP572BCPZ-R2 is an ultrafast single-supply comparator fabricated on Analog Devices' proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. It features CML output drivers and latch inputs, designed for high-speed signal processing applications. The device operates with a single positive supply ranging from 3.1 V to 5.4 V. Key electrical specifications include a typical propagation delay of 150 ps at 200 mV overdrive, a minimum pulse width of 80 ps, and an equivalent input rise time bandwidth of 8 GHz. It exhibits low deterministic jitter of 10 ps and random jitter of 200 fs. The component includes on-chip 50 Ω input terminations and resistor-programmable hysteresis.

Feature Summary

• Ultrafast SiGe performance with 150 ps propagation delay and 8 GHz equivalent input bandwidth
• CML output stage capable of directly driving 400 mV into 50 Ω transmission lines
• Integrated differential latch control for capturing input states
• Robust input protection preventing output phase reversal during overdrive

Applications

• Clock and data signal restoration and level shifting
• Automatic test equipment (ATE)
• High speed instrumentation
• Medical imaging and diagnostics
• Threshold detection and peak/zero-crossing detectors

Procurement Notes

Verify the specific ordering suffix R2 corresponds to the required tape and reel packaging configuration before procurement. Confirm that the voltage supply requirements align with the specified 3.1 V to 5.4 V range for both input and output stages. Ensure proper bypassing capacitors are included in the design to support the high-frequency operation characteristics defined in the datasheet.

Selection Notes

Select this component when ultrafast response times and low jitter are critical for system timing accuracy. The CML output interface requires compatible termination networks and power supplies distinct from standard logic families. Consider the extended industrial temperature range if the application environment exceeds standard commercial limits. Evaluate the need for latch functionality versus continuous comparison mode based on signal integrity requirements.

Part Context

This part belongs to the ADCMP572/ADCMP573 family of ultrafast comparators manufactured by Analog Devices Inc. The ADCMP572 variant specifically utilizes CML outputs, whereas the ADCMP573 offers RSPECL outputs. Both share the same core SiGe architecture and package form factor but differ in output driver compatibility and latch enable voltage thresholds.
